KLTV 7's encounter with Dr. Nichols and his attorney, Bradley Lollar of Dallas, was brief.

"We just started working on this case, and there's a long way to go," Lollar said.

But Smith County District Attorney, Matt Bingham, says that is the same confession Nichols gave to police the night of the murder. And he says, that is enough.

"So what we have is someone who as admitted to killing his wife, that's a tremendous concern to us because he is out there in the public," Bingham said.

According to the arrest affidavit, Nichols got into an argument with his wife the night of June 29th. The affidavit says Nichols went out to his vehicle to get his gun and went back into the residence in South Tyler. After further argument, the affidavit says he then shot Rosiland twice.

He was charged with murder, and was later released on a 750 thousand dollar bond.

According to Bingham, the Smith County grand jury made a probable cause determination today that Dr. Nichols did commit the offense of murder--so they went ahead with the indictment.

"Because it's a violent crime, because of the evidence in the case and as a safety concern, we feel like the bond should be doubled, but then again we can only make that recommendation to the court, which we've done," Bingham said.

Moments after the indictment was handed down this afternoon, Bingham asked Judge Christi Kennedy to double Nichols' bond from 750-thousand dollars, to one and a half million dollars.

He says he made that request to protect Rosiland Nichols' family.

"Here is a man who's admitted to killing their grandmother, their mother, and he's out on bond after being indicted and admitting to it," Bingham said. "We want that family to feel safe."

Bingham says Judge Kennedy did not increase Nichols' bond, a decision Bingham says he respects, but does not agree with.

"Ultimately it's up to them and their given that authority, and whatever they deem appropriate that's what they will do."

Which means Dr. Nichols was not re-arrested on Thursday. His bond remains the same--as does his story of what happened that Friday night nearly two weeks ago, in a home, in a quiet South Tyler neighborhood.
